No, it is not true that Albert Einstein had a really bad memory. In fact, Einstein had a remarkable memory and cognitive ability. He was known for his exceptional intellect and ability to recall complex mathematical concepts and scientific principles.
The misconception about Einstein having a poor memory might have originated from anecdotes or quotes attributed to him that suggested forgetfulness in certain areas. However, these remarks were often taken out of context or exaggerated. Einstein's forgetfulness, if any, was likely within the realm of normal human variability and not indicative of a significant memory impairment.
It is worth noting that memory performance can vary depending on the type of information being remembered and individual differences. While Einstein was undoubtedly a brilliant physicist, his memory abilities, like those of any individual, could have had strengths and weaknesses in different domains. However, overall, there is no credible evidence to support the claim that Einstein had a bad memory.
